About This Game
Step into a vast sci-fi universe in The Expanse: Osiris Reborn, a story-driven action RPG set in the 24th century where humanity has spread across the solar system—but survival is still a constant struggle. You play as a Pinkwater Security mercenary whose routine stop on the asteroid Eros suddenly turns into a deadly crisis. Trapped in a lockdown and pulled into a massive conspiracy, you must fight to survive and take control of one of the most advanced ships ever built.
Create your own captain and choose your background as an Earther, Martian, or Belter. Each choice shapes your identity and influences how the world reacts to you. As the story unfolds, every decision you make impacts your journey, alliances, and the fate of those around you.
You won’t be alone. Build a crew of skilled companions, each with their own past, personality, and motivations. Your relationships with them evolve based on your leadership and decisions—trust can grow, or everything can fall apart. Your ship becomes more than just transport; it’s your home, your base, and the heart of your team.
Combat takes place in third-person, featuring tactical, cover-based gunplay and powerful abilities. You can bring two companions into battle while others assist remotely by hacking systems or distracting enemies. Quick thinking and smart commands are key to surviving dangerous encounters.
Travel across iconic locations like Ganymede, Mars, Ceres, and Luna. Explore detailed environments, interact with locals, uncover hidden secrets, and shape events through your choices. Each location offers a unique atmosphere, from crumbling colonies to politically tense strongholds.
